Browse source 
ARM:
 * fix incorrect huge page mappings on systems using the contiguous hint
   for hugetlbfs
 * support alternative GICv4 init sequence
 * correctly implement the ARM SMCC for HVC and SMC handling
 
 PPC:
 * add KVM IOCTL for reporting vulnerability and workaround status
 
 s390:
 * provide userspace interface for branch prediction changes in firmware
 
 x86:
 * use correct macros for bits
